MEANS FOR SECURING RAILS 'IO METAL TIES.

Specification of Letters Patent.

Patented May 14, 1912.

Application filed July 18, 1911. Serial No. 639,446.

To all whom it may concern:

Be it known that we, WILLIAM H. Mon- GAN and WALTER V. HARTZELL, bothciti- Zens of the United States, residing at Alful Improvements in Meansfor Securing Rails to Metal Ties; and we do hereby declare the followingto be a full, clear, and exact description of the invention, suchaswhich it appertains to make and use the same. I

Our invention relates to an improvement in-means for securing rails tometal ties.

In a pending application filed by us March 18, 1911 Serial Number615,397, the rails are supported on parallel rail carrying members ofZ-shaped ties, and are secured thereto by spring clamps engaging thebase flange of the rail, and integral shoulders depending from theunderside of the top flange of the tie. With such construction it is notpossible to adjust the rails to compensate for wear, except bydisconnecting the rail and turning it end for end, nor is any provisionmade for taking the side thrust on the rails except by the springclamps.

The object of this invention is to provide for the ready and quickadjustment of the rails to compensate for wear without removing therails, and also for taking the side thrust of the rails.

With these ends in view our invention consists in a chair intermediatethe rail and tie and having oppositely disposed flanges which engage theouter edges of the base flange of the rail and the top flange of thetie, and spring clamps embracing said flanges and engaging the latterand also the adjacent flanges of the rail and tie.

Our invention further consists in the details of construction as will bemore fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in plan showing severalties with rails thereon. Figs. 2 and 3 are views in section through therail, tie, chair and securing devices. Fig. 1 is a view in perspectiveof a section of a tie showing the recess for the chair, and Fig. 5 is aview in perspective of the chair.

wider than its top flange 3. This tie is bent into Z or other shapewhich provides two parallel rail supporting sections. Each railsupporting section of the tie, is provided in its top flange or member,with a transverse recess extending throughout the width of said topmember. These recesses are formed by swaging, pressing, rolling, or inany other approved manner, and form depressed seats for the chairs 6,one chair being located in will enable others skilled in the art to eachseat. Each chair is of a thickness equal to the depth of its recess, sothat when seated therein it will rest flush with the top surface of therail supporting section of the tie, and each is provided at one end withan upwardly projecting flange 7, and a depending flange 8, and at itsother end with an upwardly projecting flange 7 and a depending flange 8.The two depending flanges 8 are adapted to engage the side edges of thetop flange 3 of the tie, and support the chair against endwise movementand side thrust of the rail, while the chair is prevented from moving orcreeping in the direction of the length of the rail, or rail supportingmember of the tie, by the side walls 5 of the recess 5.

The upwardly extending flange 7 is of greater thickness than the flange7 and in assembling the parts, the chairs 6 are so placed, that theirthicker flanges 7 will be on the inner side of the rail. After the innerside of the rail has worn sufliciently to necessitate rearranging of therails, the spring clamps to be hereinafter referred to are removed, andthe rail jacked up thus releasing, the chair and permitting the latterto be turned end for end, thus bringing its narrower flange 7 to theinner side of the rail. This reversal of the position of the chair,shifts the rail toward its companion rail a distance equal to thedifference in thickness of the flanges. By this means the wear may betaken up, first, by the adjustment of one rail, and subsequent wear, bythe adjustment of its companion rail.

WVe have referred to the flanges 7 and 7 as varying in thickness, andwhile we have so shown them, it is clearly evident that the results arenot necessarily due to any differences in thickness of the flanges, butto the relative location of the inner faces of said flanges, to theinner face of the ad- The tie 1 is preferably of Ishape in cross jacentdepending flange 8. In the present section, its base flange 2, being'preferably instance the vertical plane of flange farther removed fromthe plane of the inner face of its depending flange, than the flange 7is from its companion flange 8 hence a reversal of the chair operates toset its rail nearer to or farther away, as the case may be, from itscompanion rail;

The lower flanges 8 are spaced to straddle the tie and bear against theside edges thereof, and project below the latter, and the top flanges 7and 7 are properly spaced to receive the base flange of a rail, andproject above the latter as shown in Fig. 2.

When the parts are thus assembled, the chair will be held in its seat bythe rail, and will operate to take all the side thrust, and they arelocked together by the clamps 9. These clamps are made preferably ofvanadium steel, or other hard, tough and finely grained steel or ironalloy, heat treated if necessary, and of a size sufficient to withstandthe strains and shocks to which they are subjected. Each consists of anupper jaw 9 adapted to bear on the upper surface of the base flange ofthe rail, and an integral lower jaw 9 adapted to bear against theunderside of the top flange of the tie, the normal space between saidjaws being some what less than the thickness of the assembled parts, sothat when the clamps are in place they will be under tension.

The flanges 7 and 7 and 8 project, as explained, respectively above thebase flange of the rail, and below the top flange of the tie, and arecentrally concaved or dished as at 10, to receive the convex front edgesor shoulders 10 of the jaws 9 and 9 of the clamps 9. The clampstherefore bear directly against the rail and tie and hold the formerdown onto the latter, and also against the upper and lower flanges ofthe chair, and are prevented from outward displacement by the latter.

The jaws of the clamps 9 are, normally, not separated sufliciently totake in the flanges of the rail and tie, consequently are under tensionwhen fully lapping both flanges, hence when the parts are assembled andlocked by the clamps, the rail will be held solidly in place on the tieby the clamps, and the latter locked against the possibility ofaccidental displacement.

The clamps are driven on, lengthwise the flanges 7, 7 and 8, until theshoulders 10" thereon seat themselves in theconcavities or recesses inthe flanges. This endwise driving of the clips onto and along theinclined flanges of the rail and tie puts the clips under tension, whichexperiments have demonstrated is suflicient to hold the rail in place.

If a clamp should break, or become dislodged, there would be no chancefor derailment, as the outer upper flange and lower inner flange of thechair would prevent spreading of the rail, and there would be notendency for the rail to turn, as the resultant of the wheel pressure onthe rail always falls within the base of the rail, hence the onlypressure to which the rail is subjected is an outward one which is takencare of by the flanges of the chair.

It is evident that many slight changes might be resorted to in therelative arrangement of parts shown and described without departing fromthe spirit and scope of our invention; hence we would have it understoodthat we do not wish to confine ourselves to the exact construction shownand described, but consider ourselves at liberty to make such changes asfairly fall within the spirit and scope of our invention.

Having fully described our invention what we claim as new and desire tosecure by Letters-Patent, is

1. The combination of a rail, a tie, a chair located thereon andprovided with upwardly and downwardly projecting flanges, the lowerflanges engaging the sides of the tie and the upper flanges the edges ofthe base of the rail and a spring clamp at each end of the chair, eachclamp engaging the adj acent edges of the tie and rail.
